We have newly cloned this instance. However when i login first time in the day, I am getting the above message.
then Immediately after clicking on logout and login , i can able to login any number of times with out any issues.
After few hours, if I try to login again I am getting the same message.
So i need to logout & login to get the connection back again.
Application version: 12.1.3
Db version: 12c
Can someone can suggest please ?
